San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

Tips On Removing A Rat Stuck In A Dumpster
If you have a rat stuck in your dumpster, please, don't forget that this is a scared creature that is now under a lot of pressure and fear for its life. Try not to additionally irritate it or mess around with it, as it might attack you, trying to protect itself. Rats carry illnesses which they can transfer directly through bites, scratches, or if their saliva drops on an open wound on your skin.
Place a lethal snap trap inside the dumpster. Accurately managing rats implies eradicating the vermin. You will need to do this as fast as possible as to not prolong the rat's suffering. Killing a rat with a deadly wooden snap trap is the most accommodating method of disposing of that rat. The rat will be frightened, so you might want to smear some peanut butter on this trap. Leave the scene, and return two or three hours later to check whether the problem is solved. If the rat was caught, use a fabric, towel, or gloves to place the carcass in a fixed plastic holder, pack or sack, which you will then be able to toss in a garbage sack. Most urban areas will permit you to discard rat remains in your garbage bin; however, you should first check your local laws.
You can also help the rat escape. You might not have any desire to kill the rat out of the blue, and would instead like to assist it with liberating itself to continue its life. The rat is stuck presumably in light of the fact that the dumpster isn't full enough, and it hasn't got anything to climb on. Toss in some more trash, or add a branch or something comparable for the rat to move up on. Stay away or leave the scene completely.
If all else fails, you can always call a wildlife removal expert.
